Perhaps you should try some spelling variations:
thieu nien » thien nhien
cua triet » cua viet, su triet, va triet
thanh va » thanh van, thanh ha, thanh ve
nien cac » vien cac, dien cac, bien cac
hanh va » hang va, hanh vi
nang ma » tang ma, sang ma, nang cao
cac xuc » cam xuc, cac nuoc, chat xuc
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach y) OR (sac ky)) nang ma hoi. thieu nien cac xuc va ((thanh va) OR (hanh va)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach y) or (sac ky)) nang ma hoi. thieu nien cac xuc va ((thanh va) OR (hanh va)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: te ((sach y) or (sac ky)) nang ma hoi. thieu nien cac xuc va ((thanh va) OR (hanh va)) cua triet*.
